Vehicles carrying evacuees during a nuclear emergency are subject to contamination inspections, and the operation of screening by measuring tires and wiper are required. The introduction of portable radiation portal monitors for vehicles is expected to be quick tire inspections, however, it is difficult to inspect the tire and the wiper at the same time, so further speeding up the inspection process is an issue. In this study, we attempted to discriminate each type of contamination by using a different the new set up of detectors for the purpose of simultaneous inspection of tires and wiper. We will report the usefulness of the new set up and the results of simulation calculations of detector response under realistic contamination assumptions.
